Predicting en-route winds
Hello,
I am just wondering if anyone has a suggestion for an alternative method/website or data source that they use for forecasting en-route winds for the completion of a VFR navigation plog.
I currently use the Met Office F214 spot wind charts for deciding on the en-route wind for legs/whole flight as required - and it often tends to be slightly ambitions in terms of wind speed resulting in a lot of drift
I am just wondering whether there is a more accurate or improved way of getting en-route wind data for plogs?
